CNC Machine Operator and Programmer Interview Questions and Answers

G17, G18, and G19 are G-codes used in CNC machining to specify the plane of operation.

• G17 is used to set the XY plane as the plane of operation.

• G18 is used to set the XZ plane as the plane of operation.

• G19 is used to set the YZ plane as the plane of operation.

• These G-codes are essential for programming CNC machines to ensure correct tool movements and orientations.

• For example, G17 would be used when machining a flat surface on a workpiece.

• Understanding and correctly using the...read more

Turning in CNC machine refers to the process of rotating a workpiece on a lathe while a cutting tool removes material to create a cylindrical shape.

• Turning is a common operation in CNC machining, especially for creating cylindrical parts like shafts, rods, and tubes.

• During turning, the workpiece is clamped and rotated while a cutting tool moves parallel to the axis of rotation to remove material.

• The cutting tool can be stationary or moved along the workpiece to create differe...read more

CNC stands for Computer Numerical Control.

• CNC is a manufacturing process that uses computerized systems to control machine tools.

• It involves the use of pre-programmed software to dictate the movement of machinery and tools.

• CNC machines are capable of producing highly precise and complex parts.

• Examples of CNC machines include milling machines, lathes, and routers.

These are methodologies and tools used in manufacturing for process improvement and efficiency.

• 4m change refers to making changes in manpower, methods, materials, and machines to improve processes.

• 7qc tools are a set of quality control tools used to identify and solve production problems.

• TPM stands for Total Productive Maintenance, a method for improving machine reliability and reducing downtime.
